Utility model content
The purpose of this utility model is to provide and a kind of solves the problem that rotor unbalance weight is too much, it is ensured that steam turbine generator safe and reliable operation.
For achieving the above object, this utility model adopts the following technical scheme that rotor of steam turbo generator balanced structure, including rotor, this rotor is rotor of steam turbo generator, the outer peripheral surface of rotor is provided with axially extended mounting groove, and mounting groove circumferentially interval is arranged, and is equipped with an axially extended rotor slot wedge in each mounting groove, axially spaced on described rotor slot wedge several balance screw is set, balance screw is provided with mass screw；The groove bottom of rotor slot wedge and its place mounting groove is that interval is arranged.
The mass screw arranged in balance screw is the first mass screw or the second mass screw or the 3rd mass screw, the length of the first mass screw is 12mm-18mm, the length of the second mass screw is 20mm-25mm, and the length of the 3rd mass screw is 30mm-40mm.
All balance screws are respectively provided with in partial amt balance screw in the first mass screw, partial amt balance screw to be respectively provided with in the second mass screw, partial amt mass screw and are respectively provided with the 3rd mass screw.
The weight of described rotor is 18t-30t, and described first mass screw, the second mass screw, the 3rd mass screw are M16 screw.
The weight of described rotor is less than 18t, and described first mass screw, the second mass screw, the 3rd mass screw are M12 screw.
Rotor of steam turbo generator balanced structure described in the utility model, when ensureing engine health and reliability, by boring multiple screw on generator amature slot wedge, according to generator amature imbalance weight number in rotor slot wedge balance screw increase and decrease mass screw or change Different Weight mass screw, owing to rotor slot wedge is distributed at generator amature circumferencial direction, quantity is many, uneven weight adjustable extent is big, thus a difficult problem too much for generator amature imbalance weight is solved, reduce steam turbine generator and run the risk that rotor amount of unbalance is too much, ensure that steam turbine generator safe and reliable operation, there is simple in construction, safe and reliable, action effect clear advantage.

Detailed description of the invention
Rotor of steam turbo generator balanced structure shown in Fig. 1-Fig. 8, including rotor 1, this rotor 1 is rotor of steam turbo generator, the outer peripheral surface of rotor 1 is provided with axially extended mounting groove, mounting groove circumferentially arranges multiple uniformly at intervals, all plugging an axially extended rotor slot wedge 5 in each mounting groove, rotor slot wedge 5 is strip.
The two sides of described rotor slot wedge 5 are provided with a positioning convex 10 respectively, positioning convex 10 is axially extending, mounting groove includes two trough wall surfaces 11 and is connected to the groove bottom 12 between two trough wall surfaces 11, each trough wall surface 11 of mounting groove is equipped with axially extended locating slot, rotor slot wedge 5 inserts in corresponding mounting groove, two positioning convex 10 of rotor slot wedge 5 correspondence respectively is inserted in two locating slots on two trough wall surfaces 11 of mounting groove, the groove bottom 12 of rotor slot wedge 5 and its place mounting groove is arranged for interval, the medial surface 9 towards rotor 1 centrage side of rotor slot wedge 5 and the groove bottom 12 of this rotor slot wedge 5 place mounting groove are arranged for interval.The both ends towards the lateral surface 7 outside rotor 1 of rotor slot wedge 5 are equipped with end grooves 8, end grooves 8 axially extend to on the end face of the rotor slot wedge 5 of this end grooves 8 homonymy.Two positioning convex 10 of rotor slot wedge 5 both sides between the lateral surface 7 and medial surface 9 of this rotor slot wedge 5.
Axially spaced on described rotor slot wedge 5 several balance screw 6 is set, balance screw 6 is provided with mass screw, the mass screw arranged in balance screw 6 is the first mass screw 3 or the second mass screw 2 or the 3rd mass screw 4,3rd mass screw 4 is long mass screw, second mass screw 2 is moderate-length mass screw, and the first mass screw 3 is short mass screw.The length of the first mass screw 3 is 12mm-18mm, and the length of the second mass screw 2 is 20mm-25mm, and the length of the 3rd mass screw is 30mm-40mm.
The nominal diameter of all balance screws 6 (all balance screws 6 refer to all balance screws 6 on all rotor slot wedges 5) is all identical, being respectively provided with in partial amt balance screw 6 in first mass screw 3, partial amt balance screw 6 to be respectively provided with in the second mass screw 2, partial amt mass screw in all balance screws 6 and be respectively provided with the 3rd mass screw 4, first mass screw the 3, second mass screw the 2, the 3rd mass screw 4 arranges some all in accordance with needs.
